Engine Pro/Fel-Pro Co-Branded Performance Gasket Sets

Engine Pro has partnered with Fel-Pro to create an exclusive line of co-branded performance gasket sets. Engine Pro performance sets eliminate the waste that results from buying a typical full set, then buying specific performance gaskets and throwing duplicates away. These sets include all the major gaskets required, including Fel-Pro performance head gaskets, valve cover gaskets, exhaust header gaskets, oil pan gaskets and rear main seal. These sets do not include valve stem seals and intake gaskets, allowing customers to specify their precise requirements.Download pdf >
